Abstract With the rapid development of micro‐energy harvesting technology, noise has great potential as a new type source by developing high‐performance acoustic energy harvester (AEH). Nevertheless, challenges from are low density, multi‐frequency mixed sound, and unstable sound pressure. Piezoelectric‐based AEHs proposed solution, but most reported devices need to work at certain frequency very high pressure, exhibit disadvantages being bulky heavy when using an extra sound‐pressure...
The purpose of the study was to determine hardness and fracture toughness dental yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) manufactured by digital light processing (DLP) technology its clinical prospects.The experimental group DLP-manufactured zirconia, control milled zirconia. investigated under a range test loads (0.49 N, 0.98 1.96 4.90 9.81 29.42 49.03 98.07 196.1 N). Meyer's law applied describe indentation size effect (ISE). Meanwhile, PSR model MPSR were utilized...
Metal halide perovskite and its derivatives show great promise in X-ray detection. However, large-scale fabrication of high-quality thick films is still full challenges due to the complicated crystal nucleation process that always introduces lots cracks or pinholes final film. Here, a MA3Bi2I9 film was fabricated by cost-effective, scalable spraying process, MACl used as an additive effectively tune crystallization process. As result, dense constituted large grains obtained, which has high...
Objective . To evaluate the influence of screw‐tightening methods on immediate and long‐term stability dental implant screw joints. Methodology A total 150 implants three different systems with diameters were used in this study. Each group was divided into subgroups ( n = 5), according to tightening (A—tightening recommended torque retorque after 10 min; B—tightening torque, then loosening retorque; C—tightening only once). The operating time assemblies recorded. Ten minutes later, removal...
Abstract Fretting damage at the dental implant–abutment interface (IAI) is a critical factor of implant failure, and it has been investigated using fatigue cycle (FC) loading tests. For first time, we applied chewing (CC) onto IAI to simulate masticatory movements. It was found that more serious furrow wear induced by sliding forces present under CC loading. Furthermore, four types metal debris markedly higher torque loss rate were observed after undergoing both cyclic loadings. Such can...
This study aims to investigate the gradient nanomechanical behavior of dental fluorosis enamel and provide appropriate selection criteria for restorative materials. The properties outer, middle, inner layers normal tooth enamel, mild severe were tested by nanoindentation under an applied load 2000 μN holding time 30 s. nanotribological then evaluated through nanoscratch tests 1000 μN. In addition, property outer layer was compared with that four materials, namely, lithium disilicate...
Abstract Glass-fibre-reinforced polyetherketoneketone (PEKK-GF) shows great potential for application as a dental implant restoration material; however, its surface bioinertness and poor antibacterial properties limit integration with peri-implant soft tissue, which is critical in the long-term success of restoration. Herein, functional magnesium (Mg) silver (Ag) ions were introduced into PEKK-GF by plasma immersion ion implantation (PIII). Surface characterization confirmed that morphology...
This study aimed to comparatively investigate the effects of accelerated aging on physical and biological features zirconia manufactured by digital light processing (DLP) conventional subtractive manufacturing (SM) with similar composition.Both DLP- SM-fabricated samples (7 mm × 7.5 1.5 mm) were grouped according (134 °C, 0.2 MPa, 100% humidity) times, including 0 h, 5 10 h. Phase assemblage surface topography different technologies evaluated before after aging. The human gingival fibroblast...
To evaluate the effects of different hydrofluoric acid (HF) concentrations and etching times on surface topography, roughness, resin bond strength to ceramic-coated zirconia (CC), to compare them with alumina air-abrasion combined 10-MDP (AA).AA CC specimens were divided into 12 groups (N = 10). The etched HF at (5% or 9.5%) for various durations (0 min, 1 2 3 5 min 10 min). morphology was analyzed using SEM. Energy-dispersive x-ray spectroscopy (EDS) diffraction (XRD) performed chemical...

Remineralization is confirmed as a feasible method to restore early enamel caries. While there evidence that the 8% arginine toothpaste has good remineralization effect by increasing surface microhardness, repair on wear-resistance and nanomechanical properties still remains unclear. Therefore, this research was conducted reveal nanotribological changes of caries after remineralized with toothpaste. Early were created in bovine blocks, divided into three groups according treatment solutions:...
